When Cameron was re-elected in 2015, he won 60 percent of the vote in his constituency.

The anti-Brexit Liberal Democrat party saw its support skyrocket in this election, gaining 30 percent of the electorate from just seven percent in the 2015 election. Liberal Democrat candidate Liz Leffman won 11,611 votes.

Renewed Lib-Dem support was enough to knock the UK Labour Party into third place after it won 14 percent of the vote.

Tonight’s #WitneyByElection result is the largest swing from Conservative to Liberal Democrat in a by-election since 1997.

The swing towards the Liberal Democrats in a Conservative heartland suggests the Tories could face a stronger than expected challenge in the UK’s 2020 general election.

Witney voted 54 to 46 percent in favour of remaining in the European Union during the June 23 referendum.

Indeed, the Witney by-election was seen in some quarters as the first litmus test for new Prime Minister Theresa May and its result may lead some to question her stewardship of the party and the country.

Tonight’s result shows that we are the only party that can win seats off the Tories and deny them a majority in 2020. #WitneyByElection

Courts ran a campaign promising to improve roads and local infrastructure, increase the numbers of affordable homes to assure local residents don’t get priced out of the region, increase support for local businesses and finally improve the access to and delivery of high speed internet.

Cameron congratulated Courts on his election victory, saying he would be a “great” MP.

Many congratulations robertcourts - you’ll be a great MP and representative for Witney and West Oxfordshire.
